In Super Smash Bros. for Nintendo 3DS/Wii U, Dragon Rush is a custom move for Charizard, replacing Flare Blitz. When used, Charizard will dash at the opponent while spinning. When the move makes contact, it will carry the opponent while repeatedly damaging them. Unlike Flare Blitz and Blast Burn, Dragon Rush will not cause Charizard to damage itself when used. Mega Charizard X uses the same move when the A button is pressed.
